SPECIFICATION forming part of Letters Patent No. 284,462, dated September 4, 1883.

Application filed June 20, 1883. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS Mani-IAN, of Brooklyn, in the con nty 01' Kings State of New York, have invented certain new and useful Improvements in Railroad-Axles, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification,in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improvement, shown with the wheels applied. Fig. 2 is a seetional end elevation of the same, taken through the line mm, Fig. Fig. 3 is a sectional side elevation of the same, taken through the line y y, Fig. 2. Fig. 4.- is an end elevation of the same, the axle being shown in section. Fig. 5 is an elevation of a part of one of the inner rings.

The obj eet of this invention is to prevent the sliding of wheels upon the rails of steam and horse railroads, and the strain, wear, and loss of power consequent upon such slidin The invention relates to a llllllOitd-itXlClllZldG 111 two parts, provided with collars at a suit able distance from their ends, 'aud'liaving a flanged and ribbed sleeve fitted upon them between the collars. Upon. the flanges of the inner sleeve is shrunk an outer sleeve, the ends of which project over the collars oi the axle and rest in rabbcts in rings which st in rainbets in two-part rings placed upon the axle at the outer sides of its collars, and secured in place by bolts passing and through recesses in the flanges of the in nor sleeve. Washers are placed between the two rings, so that the wear can be readily taken up, as will be hereinafter fully described.

A represents the axle, which is made of steel or l on, and is provided with wheels B in the ordinary manner. The axle A is made in two parts, which are placed in line with and abut against each other, and have collars Gformcd upon them. Upon the adjacent parts of the axle A, and between the collars C, is fitted the steel casting or cast-iron sleeve 1), which is formed with flanges E around its ends and center, and wit four (more or less) ribs F upon its outer surface, extending from, the center flange, E, to the end flanges. Upon the flanges of the inner sleeve, D, is shrunk a wroughtthrough the said rings iron sleeve, G, the ends of which project alittle beyond the ends of the said inner sleeve, 1), so as to overlap the collars U, shown in Fig. 3.

H are steel rings, which are made of the same outer diameter as the outer sleeve, G, and are rabbeted to receive the ends of the said sleeve G, so that the outer surfaces of the said rings and sleeve will be flush with each other. The inner diameter of the rings G is such that the said rings can pass over the collars U of the axle A.

Upon the axle A, at the outer sides of the collars C, are placed steel rings 1, which are made in two parts, as shown in il ig. 4, so that they can be readily placed upon and removed from the said axle. 'll 1e inner sides of the outer parts of the rings I are rahbeted 1o recei ve and form seats for the inner rings ll.

Between the rings 11 .l' are placed a number of sheet-metal washers, .T, as shown in Fig. 3, so that the wear of the mvrts can be taken up by removing the washers J successively.

K are long bolts which pass through holes in the rings I H and through recesses T1 in the flanges E, as shown in Figs. 2, 3, and 4. The bolts K can be made with a head at one end and a nut at the other; or they can have nuts at both ends, as may he desired. The latter construction is shown in Fig. 3.

In the outer sleeve, G, are formed a number of openings, M, closed by sci.-ew-plugs N, so that one or another of the said m enings will always be upward when at rest, to allow oil to be readily poured into the space [ml-ween the sleeves G l), which space serves an oil-res ervoir. As the axle revolves, the ribs F and boltsKscrve as buckets to raise t he oil and cause it to flow through the recesses T1 in the flanges .l l to the space at the ends of the inner sleeve, D, where it comes in contact with the axle A and collars G. The oil also passes tln-(mgh openings O in the inner sleeve, 1), and along longitudinal grooves P-in the inner surface of the said inner sleeve, I), so that the entire -frictionsurlace of the axle will be kept thoroughly lubricated.

With this construction the axle can he used a long time without removing the oil. With this construction, also, either wheel 13, with its connected part of axle A, can move independently of the other wheel and its part of the axle within the axle-casing, thereby avoiding the usual slip, strain, friction, and wear in rounding curves, overcoming the friction due to inequalities in the circumference of the wheels and preventing the wear of the wheel-flanges incident thereto.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A railroad iLXlC made substantially as herein shown and described, and consisting of the axle A, made in two parts, provided with collars (l, the flanged and ribbed inner sleeve, I), fitted uponthe axle A, the outer sleeve, G, shrunk upon the flanges of the inner sleeve, and the mbbeted end rings, HI, and the bolts K, as set Jorth,
